To all whom it may concern:

Be it known that I, WALTER B. Gonn, 'a

citizen of the United States, residing at Blue, in the county of Erie 'andState of Penna, have invented certainnew and useful Improvements in Governors, of .which thefollowing isia specification.

a This invention is'an improvement in shaft governors for steam or internal combustion engines. Shaft governors. heretofore designed willkeep the speed constant within certain limits, but do not allow any speed variation heyondthose limits without shutting the engine down and changing the tension of the spring or the amount of weights in the governor mechanism, and only within comparatively small limits by this means.

Speed-change devices have been used in con- .nection with engines not having automatic governors, whereby the engine speed has been changed by a throttling governor or by lengthening orshortening the valve travel by ,what is known as hand-ad ustable cutofis. The former method is not economical, and the latter is complicated as well as dangerous to operate.

eccentric w Heretofore with shaft governors the go: ernor arm had a position in the governor wheel somewhere between what is known as the long-travel and the short-travel posi-, -tions, depending on --the.load on the engine.

When the engine was starting or stopping,

and was not up to full speed, the governor was in .what is known as the long-travel position; and when it was operating withany desired speed from ma mum to zero.

may be obtained in the ma' hereinafter shown. Furthermore, with my device the automatic governor is always n position to act as a safety stop and prevent the engine from exceeding a certain predetermined speed, should the load be reduced.

I (lottedIi'ries the motor continues to to the cylinder of the engine at a 'ivenload, and the speed of the engine is thereby rcduced. The speed may be reduced to a de-. siredpointwhereupon the electric connection is broken and the armature of motor ceases to revolve. If it is desired to increase the speed of the engine, connection with motor I is made" so as to revolve the armature in rc-, verse direction, which will pull sto H'into housing P. Governor arm D will follow stop H on account of the tension of governor spring '1, thereb increasing the valve travel until the desire speed is reac'hed., If the stop H is withdrawn into housing Rsg far that the valve travel is great enough to overcome the load of the engine so as to operate the engine, at its maximum speed, so

D will no longer bear against stop H but will have itsusual equilibrium with respect to spring1 WVhen operating this mec anism at duced speed, that 15, speed less than that forv which the governor mechanism is adjusted, if the loadshouldrbe reduced the speed of the engine would not exceed that forwhic the governor mechanism had been adjusted, for the reason that the overnor arm will automatically take a positlontoward the dot= ted lines or short travel position which will lessen the travel of thewalve gear. 1 Fromthe above it". will beseen that the speed of the enginemay be reduced from the normal speed for whichthe shaft gov- .ernor is adjusted, and that the Ispeedof the engine may be varied within the limits of zero-and maximum speed. It will'also be seen that this speed control is obtained by shortening the long merely lengthening or travel position or the governor.

I do not limit myself to operate this longtravel stop by means of an electric motor; but can operato-it by fluid motor or mechanical means where the power is obtained from the engine itself ,or where power is obtained from means outside of engine, either manual or mechanical.

H to obtaining this adjustment while the engine is in operation. I can obtain the adjustment 'by shutting down the engine and adjusting thestop H manually, as shown in Figmi.

Furthermore, I do not limit myself to placing this device in'the usual position as shown of the long-travel stop; but it may be located to funetion at any suitable point on the governon arts oran, gxtcn'sion t hereof, to produce similar resultsfi Iclaimr q L- In a governor, the combinatibri'oia wheel or other rotary member, a governing member movablethcreon, an adjustablestop pin carried by the'wheel for said member, 125
